Introduction Radiation refers to the phenomenon when energy in the form of waves or particles is emitted. This can include alpha particles, beta particles, and even gamma photons. Alpha particles are also referred to as alpha radiation or alpha waves, and they consist of two protons and two neutrons. What is an Alpha particle? Alpha […]
Introduction It is possible for elements in nature to change into another by various processes. Such processes are classified as nuclear reactions. For instance, nuclear decay is a type of reaction which occurs when an unstable nucleus emits energy, nucleons, and/or atoms to achieve stability. Various other types of reactions also exist. Various types of […]
Introduction All of our energy is generated by fundamental chemical and physical processes. Throughout history, this has typically been accomplished by burning carbon-based resources such as wood, coal, and gas, or by utilising the energy of the sun, wind, and water. Through two physical processes known as fusion and fission, atoms can generate vast amounts […]
Introduction By treating an aryl hydrazone of a ketone/aldehyde with an acid or a variety of metal & dehydrated metal salt catalysts, \(N{H_3}\) may be removed, leading to the creation of an indole. This process is known as the Fischer indole synthesis. By directly putting an equal molar combination of aryl hydrazine as well as aldehyde/ketone […]
Introduction A chemical is produced when primary alcohol is reacting with a carboxylic acid in the presence of sulphuric acid. The odour of this chemical is fruity and pleasant. The resulting chemical is known as ester. The chemical reaction that results in the creation of the ester is called an esterification reaction. There are three […]
Introduction The rate of reactions is a word used to describe the rate at which a reaction occurs. The concentration of the reactants is a reliable indicator of the reaction rate. One can think of the rate of a reaction as being directly proportional to the production of the product and inversely proportional to the […]
Introduction The symbol for an element is a single letter or two-letter abbreviation of the element’s full name. These symbols are helpful when writing out lengthy chemical equations that need the usage of shortened forms of complexes and elements. The number of electrons (\({e^ – }\)) and protons (\({p^ – }\)) in an atom can […]
वाक्य में प्रयोग किए गए शब्दों को पद कहा जाता है| इन्हीं पदों का व्याकारणिक परिचय देना पद परिचय कहलाता है। वाक्य में आए पदों का परिचय विभिन्न आधारों पर दिया जाता है।दिया जाता है। प्रयोग के आधार पर पद परिचय आठ प्रकार के होते है 1. संज्ञा शब्द का पद परिचय वाक्य में संज्ञा […]
काव्य को सुनने या पढ़ने में उसमें वर्णित वस्तु या विषय का शब्द चित्र में बनता है। इससे मन को अलौकिक आनंद प्राप्त होता है। इस आनंद और इसकी अनुभूति को शब्दों में व्यक्त नहीं किया जा सकता, केवल अनुभव किया जा सकता है, यही काव्य में रस कहलाता है। किसी विनोदपूर्ण कविता को सुनकर […]
